HOUSTON – A prosecutor says a Houston woman accused of stabbing her boyfriend to death with her stiletto heel had been drinking tequila with him at a nightclub earlier.

The Houston Chronicle (http://bit.ly/18tdGKL ) reports a judge decided Tuesday there was probable cause to hold 44-year-old Ana Lilia Trujillo (troo-HEE'-yoh) on a felony murder charge. She remained in the Harris County jail Tuesday on $100,000 bond.

Fifty-nine-year-old Alf Stefan Andersson was fatally stabbed Sunday at his luxury high-rise condominium. Andersson was a researcher in women's health issues at the University of Houston.

Prosecutor John Jordan told the judge the victim became angry at the nightclub after a man tried to buy Trujillo a drink. The defendant's statement says the victim became abusive at the condo.
